The Sun Hydraulics DPBBOKN (DPBBOKN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses the preset value. Notably, pressure at port 3 adds directly to the valve's setting; hence, it may not be suitable as a work port in certain circuits. For such scenarios, a four-port version might be preferable. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and having identical flow paths. The DPBBOKN is not bistable and can modulate between two positions. When pilot pressure exceeds its setting, pilot flow could become significant; thus, referring to performance curves for pilot consumption versus load pressure is advisable. If this presents an issue, opting for a direct-acting version might be beneficial. This model features Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining discrepancies. It fits into a T-11A cavity with a series capacity of 7 gpm (28 L/min) and has a maximum operating pressure of 5000 psi (350 bar). Factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve exhibits maximum leakage of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar), ensuring efficient operation under specified conditions. Additional specifications include an adjustment range requiring up to five clockwise turns for increased setting, with specific torque values for installation and locknut adjustments provided for precise setup. The model weighs .60 lb (0.30 kg) and uses Viton seal kits for optimal sealing performance.

Normally closed, pilot-operated, 2-way directional cartridges are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve setting. If this is a problem, the direct acting version of this valve would be a solution.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
